To all whom it may. concern.-

Be it known that I, WILLIAM A. BROWN, 'a

citizen of the United States, residing at Oakland, in the county of Alameda and State of which the following is a specification.

` My inventionrelates to a device for-heating water by means vof an electrical-current and a device by whicha resistance v is produced to raise the. temperature ofthe water in the containing vessel.

. It comprises combinations-of parts and details of construction, which will be more fully explained by reference to the accompanying drawings, in which- Figure l is a sectional view of my device.' Fig. Zis an outside view of a corrugated tube.

'It is-the object of my invention to provide a means for rapid heatingoi' liquids by the immersion of the heater mechanism Within the liquid.

A's shown in the drawings, A is a hollow tube having perforations in its sides, as shown at 2.

3 is the part through which heat is com municated to the water. This part is here shown in the form of a bar of smaller diameter than the interior of the tube and having grooves, channels, or corrugations of any desired character formed upon its surface, the

object being in any construction to ,makeas' large a contact-surface for the water as possible. The ends of this bar are provided with non-conductors, as at 4 and 5. The non-conductor 4 is of such greater diameter than the bar that it prevfnts contact of thel bar with the sides of the tube near one end. The other-non-conductor-5 forms an insulation between the bar and the head 6, which iits into one end of the tube.

7 represents the conducting-wires" which are connected with the opposite poles ol a source of electrical energy, and one ot these wires is connected with the head el' cap o cud` the other *with the bar 3.

is these parts are not in direct eleciri'mi imi; smuicatiou, it `will be manifest that the elwlrucul current pass ing through the circuit must include as a .means orA transmission a body of water which is inclosed within the tu'be A and which forms the resistance. The water is constantly circuiting through thetube by' reason of the openings in the side' of the tube, which may ralso be corrugated, if desired.

A device .thus constructed* may 'be im mersed in any vessel containing-water, and

--the water will be heated to any desired temperature in a short space of time. i

Having thus described-my invention, what I claim, and desire' to secure'by Letters Patent, is.-

1. Animproved'water-heater.consisting'of a perforated tube having a bottom substan# tially closed and having an open top portion,

said headprovidedwith a socket, a bar within saidtube said bar anon-conductv ing portion at its lowerend adapted to restl upon` the bottoni of the tube, and having a non-conducting portion at its upper end adapted to iit the socket of said head and electrical connections between the bar and head.

' 2. An improved water-heater consisting of a perforated tube having a bottom substantially closed and having an open top portion, la head iitting the open top portion. of .the tube said head provided with a socket, a bar withnesses.
